The Barco R9829997 is a TLD+ (tele long distance) zoom lens engineered to provide exceptional image clarity and stability for professional Barco 3-chip DLP projectors. It is designed for applications where the projector needs to be placed a significant distance from the screen, such as in large auditoriums, theaters, museums, and large-scale event venues. The lens is optimized for high-resolution performance, with a specific throw ratio of 6.92–10.21:1 when used with WUXGA (1920x1200) projectors, and 7.5–11.2:1 with SXGA+ (1400x1050) projectors.

This lens features both motorized zoom and focus capabilities, allowing for smooth and precise remote adjustments after the projector has been installed. Its high-quality glass construction is designed to manage the high light output of large-venue projectors, including both traditional lamp-based units and newer laser-based systems like the UDX, UDM, and HDX series. The robust, stable mount ensures consistent, reliable performance in demanding environments, making it a durable choice for rental and fixed installations alike.
